Use the VMTSDF utility to format a control area on an unused area of the shared minidisks containing the TMC and Audit files when using the CA VM:Tape Shared Disk facility.
Use the CA VM:Tape SDC command to unlock a disk when an outstanding lock prevents the CA VM:Tape service virtual machines from completing initialization.
Because a control area resides on both the 1B0 and 1D0 minidisks, you must run the VMTSDF utility twice; once for the TMC minidisk and once for the Audit file minidisk.
Important! Use the VMTSDF program only when all of the participating CA VM:Tape service virtual machines are down, or unpredictable results may occur, including the destruction of the TMC or Audit databases.
Note: For more information about multiple CA VM:Tape systems sharing TMC and Audit files, see Shared Disk Facility (CMS TMCs Only).
